Electronic Load PLI

Electronic Loads, PLI Series

Description

The Electronic Loads of PLI

series provide a comfortable

operation by a graphical user

interface.

The highlight of the PLI series

is the extensive variety of

standard interfaces.

Apart from Ethernet, USB, RS-

232 and Analog I/O Port there is

a standard CAN interface.

GPIB can be installed as an

option (PLI02).

Programming is done in SCPI

syntax.

Functions

The units provide constant

current, constant voltage,

constant resistance and con-

stant power mode. Optionally

MPPT1) function for solar

panel test can be activated. In

addition, protections for cur-

rent and voltage can be set in

any mode. Dynamic operation

can be configured by up to 300

list point settings. A data ac-

quisition function allows to

store measurement data on an

external USB flash drive.

Optionally (Option PLI20) the

MPPT Function can be enabled.

Loading capacity

The model range covers three

power classes with 600 W,

1,400 W, 2,100 W and 3,200

W continuous power rating.

In addition the models up to

300 V have an overload capa-

bility. The height and duration

of the possible overload de-

pends on the temperature of

the power stage. The unit

indicates the currently possible

overload. Therefore the units

can be used even for consider-

ably more powerful applica-

tions for short time.

Protections

Current limitation

Power limitation

Over-temperature protec-tion

Over-voltage protection

Reverse polarity protec-tion up to rated current

Under-voltage indicator

Protection of the GND lines at the Analog I/O Port

Tools

The delivery includes comforta-

ble tools for PC control.

Analog I/O Port

The standard Analog I/O Port

provides the following func-

tions:

Load setting C and V

Analog setting of C and V protections

Load on-off

Voltage monitor output

Current monitor output

Trigger input

Trigger output

Digital input and pro-grammable output

Galvanically isolated

Analog I/O Port

(Option PLI06)

For the galvanic isolation be-

tween the Analog I/O Port and

the load terminals the PLI06

option can be installed.

Using this board prevents

ground loops and allows load-

ing of bipolar voltages with

two loads and common analog

control.

Data Interfaces

The following interfaces are

included as standard:

Ethernet

USB

RS-232

CAN

Analog I/O Port

LabVIEW driver is approved by

National Instruments.

Factory Calibration

Certificate

(Option FCC-PLIxx)

A Factory Calibration Certificate

(FCC) can be supplied with the

devices. The FCC meets the

requirements according to DIN

EN ISO 9000ff. This calibration

certificate documents the trace-

ability to national standards to

illustrate the physical device in

accordance with the inter-

national System of Units (SI).

The recommended calibration

interval is 1 year.

Ethernet + USB + RS-232 + CAN + Analog I/O Port

as standard

CC - CV - CR - CP - CCV - CVC Mode + optional MPPT

Dynamic loads with synchronized DAQ function

SCPI programming with measurement function

USB stick as measurement data memory

Protections for current and voltage
